This mounting standard was first used by Pulsar on their DN55 and DFA75 digital night vision clip-ons. It is of the bayonet type – there are two notches on each side of the bayonet. The adapter is installed in place by inserting the adapter pins into the notches and turning the adapter counterclockwise. Some adapters on the market fit directly on the bayonet, while a reducing ring (converter) is needed with others.
All the clip-ons that feature this mounting standard are front-mounted, meaning that they are mounted on the riflescope’s objective. This mounting standard should not be mistaken with the similar Pulsar Forward standard which has four notches on the bayonet instead of two.
